Solid State Driver Upgrade Update 1kW Solid State Amplifiers – 67 have been tested and calibrated. – 2 are in the queue to be tested. Completely assembled. – 1 was being tested, but needs a heat sink repair. Temperature of channel A was 20°F higher than the rest. – 3 have combiners in them, need to finish assembly. – 8 chassis built, need heat sinks. – 3 chassis need to be built, add heat sinks to those.
Solid State Driver Upgrade Update Issues – Not too many issues with testing and calibrating. Most common problem is usually an inability to match the currents to within 100mA per channel at 16dBm RF input and the output voltage at 0dBm RF input within ±1V. – Alleviated by swapping out Driver/Output FET’s. – 2 have had heat sink problems. Improper cooling on one channel. – Miscellaneous minor issues (bad IC or capacitor, etc.) – No real labor issues for now. A little behind schedule but amp testing and calibration won’t be a showstopper.
René Padilla, Matt Domeier Booster Modulator Upgrade All parts have been ordered We have 6 part time technicians making subassemblies and 3 full time technicians assembling the Modulators. There are 8 Modulators of the first batch of ten which are 25 % assembled. The other 12 Modulator are about 10 % assembled. The difficult part is the wiring. Expect the wiring to be done by the end of August.
René Padilla, Matt Domeier After the wiring installing the equipment and hooking them up should be quit easy. Maybe 2 months work. continued
High power testing of ferrite cores for new Booster ferrite bias tuners (Proton Improvement Plan) Dennis Barak On behalf of John Reid, Matt Slabaugh, and Steve Hays
What has been completed: Ferrite core samples have been obtained Low power testing of samples has been completed by Ralph Pasquinelli (Nov. 2011) – See THIS document for more detailsTHIS High power testing needs to be completed The high power testing fixture has been refurbished mechanically A high current PS has been designed and built by Steve Hays and co. – Capable of providing up to 30-kA Wednesday, May 23, 2012
Ferrite testing fixture Wednesday, May 23, 2012
High Current PS Wednesday, May 23, 2012
We are currently working on: Finish preparing the high current PS at the testing location (E48 kicker room) Connecting the high current PS to the testing fixture Initial measurements and adjustments need to be made to the fixture – Measure resonant frequency of the structure – Correct the resonant frequency through capacitive loading – Measure unloaded and loaded Q-factor of structure Complete high power test on each sample core Wednesday, May 23, 2012
